Comparing Processors

If you have two processors A and B how do you compare them to make a decision which one is bettor or offers better performance for a given price ? Unfortunately there is no single solution that can satisfy the need for all the information you are looking for. We have gathered here a set of tools and sites that you may use to get reasonable information.


Intel has its own database of launched processors that can be used to compare two or more processors. They do not have a comparison engine and you will have to manually set it up. You need to search for the first processor in Google with “Intel” as one of the search terms, the processor part number being the other. For example, if you wish to compare Intel Core i7-6700K with i5-6600K, you first search for “Intel i7-6700K” in google that takes you to the Intel website. Once on the Intel site, click on the Compare+, which makes it the first processor to be compared.


Next, you go to the google again and search for the second processor. In our example, search for “Intel i5-6600K”. This will take you to the Intel website again and click of the “compare+” again, this time for the second processors. There are now two processors on the compare basket. You may add a third processor, in the same way if you wish to compare the third processor. Once you have add the processors in the Intel compare basket, just click on the yellow “compare” button.


That brings you to the page giving you the table of two or more processors. The difference is highlighted with yellow background showing the differences.


This video shows the process of comparison.

Pros :-

1. Very good for comparison of two processors of same family
2. Highlights the differences in two processors
3. Can be used to compare more than two processors


1. Does not has the benchmark scores
2. Can not compare an Intel processor with an AMD processor

Compare Benchmark on

The Intel website does not give any information on the benchmark and also can not compare its processor with AMD processor. This is where the Passmark Score from comes handy.  Just search with the processor part number and “passmark” or “benchmark” as the search term in google and you are likely to land into the Passmark website. Do this again for the second processor, note down the benchmark numbers and do the comparison yourself.

Passmark scores are uploaded by real users, so it is a representation of  actual processor score. You may even benchmark your own desktop or laptop using the software provided by and compare your score with those uploaded by others.


Pros :-

1. Very good for  quick benchmark of two processors.
2. You can benchmark your own processor.


1. Does not show specification differences
2. Does not show side by side comparison

Check Processor details on has a good amount of detail for most of the notebook processors on its website. If you search for a notebook processor and add “” in the search term you will land into its page, that not only lists the processor specifications, but a huge number of popular benchmarks, including 3DMark, Cinebench, wPrime32 etc.

It also has a full list of processors with benchmark. You can choose any two processor and see the benchmark results.

Pros :-

1. Good amount of details, specification.
2. Also shows benchmark


1. Does not contain details of desktop and server processors
2. Does not show side by side comparison.

Check processor specification from CPU World

It also has a CPU World keeps an eye on all new processor releases and has a good collection of specification of all the processors. If you search for a processor part number you are likely to land on cpu world as one of the search results in page 1. It is a very old website and is still doing very good.

CPU Wold also started showing processor comparison.However, the comparison is listed from database which makes un unnatural and unpleasant reading.

Pros :-

1. Details and specification for every processor.
2. Lists latest processor launches
3. Also has a comparison engine.


1. Not in depth details.
2. Comparison and specification makes and un natural reading.

Details of the Processor Family and architecture

The processor clock frequency, number of cores TDP rating etc do give valuable information, but if you wish to really know the details, you may want to dig more into the details of the family to which the processor belongs. This will give you some idea about the integrated graphics and its performance, the chipsets, the details of the integrated memory. Anandtech does a very good job in bringing out the details of the architecture of the family at the the time of launch. Unfortunately, anandtech covers only the top of the line processors and does not cover the lower end models. It misses out the finer details about the lower end processor models.

Comparing Processor Prices

Prices of the Desktop Processors can be checked at Amazon and newegg. Intel website also suggests the price of its own processors. The actual price at amazon and newegg will vary depending upon the supply and demand.

The launch prices of the Intel’s notebook processors can be checked at its own website. Its website only shows the launch price, and actual current price may be slightly lower. Since notebook processors are not directly sold, a better way is to check the prices of the notebooks, and check the specification of the processors installed in the notebooks.
